@riginal application nled April 13, 19H, Serial No. 620,826. Divided andthis application led November To all whom may concern:

Be it lrnovvn that l, PAUL ll-l. BERGER, a citizen of the United States,residing at Chicago, in the county of Cook and State or' illinois, haveinvented certain new and useful improvements in Calculating-Machines, ofwhich the following is a specification.

This invention relates to calculating machines in general, andparticularly to the line spacing, escapement, tabulator, carriage returnmechanisms and other carriage control features tor a calculating machinewhich are designed to operate manually or automatically during'theoperation ot the calculating machine. 'lhis application is a division ofapplication Serial No. 620,826 tiled by the applicant on the 13th oi'April 1911.

`With the above and other objects in View as Will hereinafter beapparent, this invention consists in the construction, combination andarrangement of parts all as hereinafter more fully described, claimed,and

illustrated in the accompanying drawings, wherein:

Fig. ll is a side elevation of the esca-pement drum olf thecarriage. Fig. 12 is a section taken along the line 12 12 et Fig. l1.Fig. 13 is a vertical section taken along the line 15% 13 of Fig. e andillustrates the manual trip for operating the return of the carriage bypower.

The present invention consists in providing carriage control mechanismsfor a calculating machine whereby the various movements" thereof areautomatic and such automatic movements are determined by the operationof the calculating machine itself.

In Fig.. .l isillustrated a plan view of the entire mechanismillustrating the carriage andcarriage controlling mechanisms at the rearof the machine. Ilndirectly these carringe controlling mechanisms areset for operation by the keys of the key-board 6 which determine thevariable movements of the number bearing members 9 of the tomechanism,as illustratedv riage and the return thereof. A springA drum 258 ismounted upon one side of the machine vand' is connected by a tape 259with the carriage 254:. This spring` drutn exerts a pull upon thecarriage and causes the carriage to escape Ain the usual'manner.

Escapementflhe escapement utilized in the present invention is bothmanual and automatic and is of such a nature that it in reality acts asa tabulator. The mechanism is so timed that each time the carriageescapes a new column is presented to the type segments 337 of themachine and differs in this respect from the ordinary escapement.

A vertical shaft 262 is located at the rear of the machine adjacent tothe carriage 254 and isprovided at its upper terminal with a gear 261which meshes with the rack 256. The lower terminal of this shaft isprovided with a beveled gear 263 which meshes with a similar gear 264keyed to the shaft 265, said shaft being mounted in suitable bearings266. A shaft 268 is arranged at right angles to the shaft 265 and ispositioned to impart a rotary motion to the latter through the medium ofthe beveled, meshing gears 267 269. A disk 270a and a notched disk 270are loosely mounted upon the shaft 268 and f are secured together forsimultaneous rotation upon said shaft,"the disks being -constructed fromla single piece of material or collared or secured together in anysuitable manner. The disk 270a is provided with a plurality of outwardlyextending studs 271 which coperate with a spring actuated detent 272pivotally mounted as at 273 to arrest the movement of the disksaforesaid.

Agdisk 274 is keyed to the shaft 268 adjacent to the disk 27 O and isprovided with a pawl'v thereof. A secondary spring pressed pawl 277 isalso mountedupon a disk 274 and acts against the notched disk 27 0 tolock the same from retrograde rotationf Pivotally mounted on a suitablesupport 278 is an escapement dog 280, an extension 279 of which normallyrests against a stationary stop 282. The eseapement dog 'is providedwith va semicircular depression 281 which co-acts with the studs 271 topermit the escapement of the carriage. A tooth 291 is also provided uponthe escapementldog for the automatic operation thereof.

It is manifest that the tension, of the spring drum upon the carriagewill create a tendency through the medium of the shafts 262, 265 torotate the shaft 268, but as will be apparent from Fig. 4, the body ofthe escapement dog normallyrests against one of the studs 271 and isretained in this position by the stop 282 or spring 283 which operateagainst the extension 279 of the escapement dog. This position of theescapement dog prevents the shaft 268 from rotating by reason of thefact that the toothed disk 270 is locked to said shaft by the pawl 275and thereby overcomes the rotary tend` ency on the part of the shaft bythe spring drum.y At the same time, if it is desiredi to returnthecarriage to its initial posltlon this may be done without changing theadjustment of the escapement dog or other cooperating elements, as therotary movement of the shaft 268 will be reversed and, hence, the dogs27 7 and 275 will ride over the notches of the disk 270 While theldetent 272 prevents any movement on the part of the disks 270 and 270%'To provide for the escapement of the carriage it will be seen that ifthe escapement dog 280 is rocked about its axis the recess 281 thereinwill be alined with the stud 271 which rests against the body of thedog. This permits the spring drum to act upon ,the carriage toescape'the same as the stud 271 aforesaid enters the depression 281. Asthe escapement dog returns to its normal position under tension of thespring 283 the body of the dog will engage may be timed by regulatingthe amount of rotation which the shaft 268 is permitted to take. V'Itisobvious, therefore, that inorder that the carriage 254 may escape, theescape ment dog 280'must be rocked about its pivotal point 268. This isaccomplished by one of two methods, to-wit, automatically or manually.The method of automatically rocking the escapement dog 280 consists of-a cam 290 keyed to and mounted for reciprocatioron one of the extendedtotalizer`- power snafts 7, the caml surface of which is adapted when soset, to contact with the tooth 291 of the escapement dog, and suchcontact will rock said dog about its pivotal point at each operation ofthe machine and permit the carriage to escape. It is to be understoodthat when a calculation is performed all of the shafts 7 rotate onecomplete cycle and these shafts rotate at all times when the machine isoperated, Whether acalculationis being performed or not and,

consequently, if the -machine is being used for listing purposes only,the automatic escapement, if set, will o erate irrespective of theactivity of the tota izer.

Mounted near the base of the machine and adjacent to the escapementclutch heretofore described is a shaft 295 provided with ali upwardlyextending arm 296, the terminal of which has a lug 297 entering into agroove 298 formed in the hub of the cam 290. One terminal of this shaftis provided with a crank arm 311 connected at its outer terminal to thestem 310 of a key 309. When the key 309 is depressed the shaft 295 willbe oscillated to bring the cam 290 into vertical alinement with thetooth 291 so that when the shaft 7, carrying the cam, is rotated, thecam surface will engage said tooth.

modera l the terminal 287 of the stem will operate against a pin 288,rocking the dog 230 and permitting the escapement to operate. The

key is then returned to its initial position by a spring 289m.

Line space-The line spacing mechanism provided for the platen of thepresent inven tion is of such construction that the same mayautomatically be operated, or such automatic mechanism may be madeinactive and the platen operated manually.

n The shaft which carries the platen 255- for rotation is provided atits terminal with a gear 323, which meshes With a gear 32P keyed to ashaft 321, which shaft is secured to the carriage 251 and is adapted toreciprocate therewith. .The rotation imparted to the shaft 321 willnaturally be imparted to the gear 323 and, hence, to the platen and,consequently, in order to automatically ro- 'tate the platen for linespacing purposes'the shaft 321 must be rotated4 from the calculatingmachine. pose one of the extended shafts 7 is provided with aone-toothed gear 301, which rotates with said shaft 7 every time themachine is operated. Directly under the extended shaft ,7' carryingtheone-toothed gear 301 is a shaft 303 provided With a gear 302 keyed tosaid shaft for reciprocation, and which is adapted to be alinedat'predetermined in tervals with the one-toothed gear aforesaid,

through the medium of an arm 307 carried by the shaft 295 aforesaid,said arm having a lug 308 at its upper terminal operating in a. grove309 in the hub of the gear 302. The opposite terminal of the shaft 295to the arm 311 is provided with an arm 294; extending" in an oppositedirection to the arm 311-and connected at its terminal to a key-stern293, which at its upper terminal is provided with a key 292. Bydepressing the key 292 the shaft 295 is oscillated and the gear 302 isbrought into alinement with the gea-r 301. This oscillation of the shaftalso removes the cam 290 from alinement With the escapement dog 280. Bythis construction it is manifest that when the machine is operating; ina single column and the line space is operating automaticallythecarriage will not escape. lt is further manifest that when it is desiredto do cross-footing the carriage should escape, but 'the line spacing'mechanism should be inactive. For these reasons and from theconstruction illustrated it is apparent that when the key 292 isdepressed for automatically operating the line spacing the key 309 willbe elevated and the automatic escapement mechanism will be inactive, andvice versa. lln order to hold the shaft 295 in For accomplishing; thispun,

either of its adjusted positions a. toothed segment 299 is secured tosaid shaft and cooperates vvith the spring pressed detent 300. The shaft303 at its rear terminal is pro vided with a beveled gear 304v whichmeshes With the gear 305 keyed to the shaft 300.

Extending vertically at right angles to the shaft 306 is a shaft 314Which is provided at its lower terminal with a beveled gear 313,. whichmeshes with and is rotated from a beveled'gear 312 carried by the shaft303. 1n this manner the motion received by the shaft 303 from theextended totalizer power shaft 7 vis transmitted through the shaft 306to the shaft 314. The vupper terminal of the shaft 314e is provided witha beveled gear 315 which meshes With a beveled gear 316 carried by astub shaft 317,mounted in the bearings 313. The stub shaft also carriesa spur gear 319 which is alined with the shaft 321 mounted in thecarriage 254. The stepby-step rotation of the shaft 314 is imparted tothe spur gear 319, as bothvthe spur gear and beveled gear 316 are keyedto the shaft 317. The shaft 321 mounted in the carriage 254; is providedwith a key 32Tb extending throughout its entire length, by means ofwhich a spur gear`320 is secured to said shaft for rotation therewithand at the same. time theshaft may reciprocate through the same. Thisspur gear 320 is mounted be tween tivo statinary arms 322, through y.The gear 319 is constantly in mesh with the the gaat* 320 and as theformer rotates the latter will also rotate and impart such rotary motionto the shaft 321. This motion is imparted from the shaft 321 through thegears 321n and 323 to the platen. Thus at every rotation of thetotalizer power shaft 7, While the key 292 is depressed, which iswhenever the machine is operated, 'the platen will automatically berotated a predetermined amount. The platen is also provided at itsterminal with a knurled knob 257. by means of which it may be manuallyadjusted.

ln cross-footing, wherein the machine op, crates across the entire Widthof the platenE .prior to any line spacing, it is necessary to 'restagainst a stop 329 formed on a station-` ary part of the machine. Theterminal of the carriage is provided with an arm 330, which is adaptedto contact with the cam surface 331 on a bell crank 326. Duringcrossfooting, as has been explained, the

automatic line spacing mechanism is disconi u nected and, hence, theshaft 314 and its co operating shafts are free to rotate and are notlocked or set in coperative relation with any other elements of themachine. Hence, when the carriage is returned to its initial positionand `the arm 330 contacts with the cam surface 331 of the bell crank,said bell crank will-be oscillated to impart a rotary motion to theyratchet wheel 324 by means of the pawl 325. This rotates the shaft 314and necessarily the shaft 317 and the gears /319 and 320, and theplaten. When the carriage has escaped the arm 330 leaves the cam surface331 and the spring 332 causes the bell crank 326 to oscillate and thepawl to erzigage another tooth upon the ratchet wheel 3 Uarrz'agereturn- The carriage return mechanism involved in the present inventionis of such a nature that the carriage may be returned to its initialposition either manually or automatically from any preis keyed to theshaft 450 and meshes with' determined point or from any point during itsescapement.

' The escapement shaft 262 is provided with a gear 447 which isconnected with a gear 449 loosely mounted upon a shaft 450 through thetrain of gears 448. The carriage return clutch is mounted upon the shaft450 and is adapted to connect the gear 449 to the shaft 450 when it issodesired to return the carriage. A gear 451 a gear 452 keyed to a shaft453. This shaft 453 is provided with a beveled gear 454 at its lower endwhich meshes with a similar gear 455 keyed yto the shaft 456. This shaft456 is driven'from the constantly running motor shaft 15- through themedium of the beveled gears 17 and 457. As the motor shaft 15 isconstantly rotating the shafts 456 and 454 will also be constantlyrotating, which movement will -be imparted through the gears 452 and 451to the shaft.

450.- Hence, whenever the gear 449 is locked to the shaft 450 said gearwill rotate yand such rotation will be imparted to the shaft 262 throughthe medium of the gears 447, 448, which will return the carriage to itsinitial position.

Loosely mounted upon the shaft 450 is a cam member 458' secured to orconnected with a gear 449 to rotate therewith. Disposed below the cammember 458 is a disk 459 connected with a second disk 463 locatedadjacent thereto. A star wheel 465 is keyed to the shaft 450 adjacent tothe' disk 463. This disk 463 carries a clutch dog 464 provided' with ashoulder 470 and which is operated upon by the spring member 466 fornormally tending to throw the terminal of the dog into engagement withthe star wheel. When the dog 464 is free to be acted upon by the. spring466 the terminal thereof engages the star wheel465, which locks the disk463 to the shaft 450 `and permits the Asame to rotate therewith. A tripdog 467 is pivotally mounted as at 468 and is provided with4 arearwardly extending tail 477, the' utility of which will be hereafterapparent. Normally, the trip dog 467 engages the shoulder 470 of the dog464 and holds .the nose 462 thereof against the tension of the spring466 and thereby retains the disk 463 out of locked engagement with thestar wheel. The disk 459 carries a dog 460, operated upon by a spring461 which normally tends to throw the lnose 462 of the dog into the pathof the shoulder of the cam 458. A stop 471 is so located on a stationaryportion of the machine that it operates against the tail of the dog 460to hold the same out of the path of movement of the shoulder of the cam458. A lock dog 4911 is pivotally mounted adjacent to the lower disk 463and is provided with a tooth 490, which is received in a depression 489in the disk 463 for locking the mechanism for overthrow.

Inasmuch as the gear 449 and the cam or one-toothed member 458 operateas a single piece and the disks 459 and463 operate as an element and actindependently of the gear 449 and cam or one-toothed member 458, it willbe seen that when the dog 464 is tripped. locking the disks 459 and 463to the shaft 450, these disks will rotate with the shaft 450. Thismovement of the disks 459'and 463 causes the tail of the dog 460 todisengage the stop 471 by permitting the dog to drop into the path ofmovement of the tooth or 'projection on the cam 458. The continuedrotation of the disks referred te causes the nose 462 of the-dog 460 toContact with the shoulder or tooth of the cam 458 and rotate the samewith the disks. This movement of the cam naturally causes the gear 449to move and such movement is transmitted to thecarriage through thetrain of gears heretofore described, returning the same to its initialposition. As the disks 459 and 463 continue rotating the trip 'dog 467will engage the shoulder 470 of the dog 469 and unlock the disks 459 and463 from the shaft. It will, therefore, be seen that at each operationof the trip dog 467 the disks 459 and 463 take a complete revolutionand, hence, as the carriage only moves a predetermined distance it isnecessary to provide the dog 460 which will be carried b v the cam 458.but which prevents the return of the carriage from any predeterminedpoint until the nose 462 of the dog 460 will engage the projection ortooth of the cam 458, thus regulating the return movement of thecarriage in proportion to the escapement thereof. It is also manifestthat las the carriage escapes the gear 261 Willvrotate, imparting'such.rotation through can be so adjusted that mandara the gears 447, 448 tothe gear 449. This movement of the gear 449 causes the cam S to rotateon the shaft 450, bringing the tooth or projection thereof into closerproximity with the nose 462 of the dog 460, `hence the further thecarriage has escaped the nearer the projection or tooth of the cam 458is to the nose of the dog. 462 and, consequently, the sooner theengagement of said projection by the nose 462 of the dog 460 when thedisks 459 and 463 begin rotating with the' shaft 450.

As heretofore pointed out, the mechanism the carriage will return fromany predetermined point in its escapement to its initial position and inorder to accomplish this a mechanism for operating the trip dog 467 mustbe provided which will operate on said trip dog when the carriagereaches said predetermined point.

Mounted adjacent to the tail 477 of the trip dog 467 is a shaft 475which carries at its lower terminal a pin 476 bearing directly upon thetail of the dog- 467. rlfhe upper terminal of the shaft 474 which isconnected to a link 47 3. |This link is acted upon by a spring 472 whichreturns said crank to its original position whereby the-trip dog 467 ispermitted to engage the shoulder 47 0 of the dog 464. The movement ofthis slide upon the arm 474 is limited by a stationary stop 47 3% beseen that as the slidelis reciprocated in one direction a pressurethrough the medium of the pin 476 will he exerted upon the tail 477 ofthe trip dog 467, causing the same to release the dog 464, bell crank478 is pivotally mounted at 482 and is connected by a pin and slotconnection 479, 48@ iwith the link 47.3.

'.lhe adjustable shaft 483 is mounted for rotation in the carriage 254and is provided with a knobt485at one terminal thereof, `which carriesan adjuSt-L-the escapement thereof, an escapement cooperating with saidment ratchetv 487 that coperates with. the

spring actu-ated detent 488. By this means it is possible to rotate theshaft to any one of a number of adjusted positions locking said shaft inany one of said adjusted positions. 'lhe body of the shaft is providedwith a plurality of radiatingI pins 484 staggeredly arranged along saidshaft at predetermined intervals. By the rotation of this shaft one ofsaid pins is brought into alinement with a projection or tooth 486formed on the bell crank 478. As the carriage escapesthe pin adjusted tolie in the path of the tooth 486 will be advanced-toward said tooth andwhen the same contacts with'the tooth a pull will be exerted on theslide 47 3, creating` the required pressureupon the pin 47 6, causingthe trip dog to bereciprocated and the dog 464 released to take onerevolution from the shaft 450 to return the carriagge. A. spring-481acts upon the c i' crank 47 5 carries a crank arm llt willv 478 to makethe same yieldable as the carriage returns to its initial position.

ln order to manually operate the trip dog 467 when the shaft 483 has notbeen set as heretofore described or for any other' reason to return thecarriage to its initial position from any point in its escapement, a key492 and key-stem 493, which key-stem is piyotally connected to a yoke494, as illustrated in Fig. 13, are provided, the yoke being connectedby means of a pin and slot connection with a rod 495 pivotally connectedto the tail of the trip dogg,` 467.

Should it be desired to return the carriage from any point in itstravel, pressure may be exerted upon the key 492, which will, obviously,oscillate the trip dog 467 .to release the trip dog 464.

lt is manifest that the present carriage control is operable, in so faras the escapement is concerned, directly from the totaiizer powershafts, and that the escapement is dependent for its automatic operationdirectly upon these shafts. lln the present invention it is apparentthat the escapement in reality amounts to a tabulating mechanism for themachine, as the items are printed or listed in columns `and the entireentry in the column is printed at once; hence the escapement operatesfrom column to column and not from digit to digit. Therefore, slightmodifications inthe details of construction of the mechanism illustratedare all that is necessary to apply the present invention to anescapernent of a digital character, and to further apply the escapementas a tabulator feature on machines which require the same.
